Abstract ice patterns. Local Tarn in pre-dawn light. Looking at it now I should have tried a polariser to see if I could bring more out of the leaf like patterns. Probably caused by temp just either side of freezing for a week with fairly light winds. Ken

This pic conveys my winter experience pretty well. It's from mid March 2014, part of a time-lapse test (prior to a trip out to Grand Canyon National Park), new snow after a significant melt-off at the tail end of the second snowiest winter ever recorded in my locale.

Jack Frost. I guess this isn't a landscape, but it does say "winter" to me. We have replaced the old windows since this shot was taken, so no more patterns, sadly (the price one pays for lower heating bills). The first shot is an area of our bedroom window approximately 1.5 to 2 inches across. The other pictures are detail crops taken from the top image. Handheld, with my old Panasonic G1, and the Olympus 35mm f/3.5 macro lens (adapted from 4/3). Should have used a tripod and explored more, but I was in a hurry to be somewhere.

Wow! Your windows are much more artistic than mine. I never get frost that good.

Your windows might be too clean. Before we replaced ours, cleaning this particular window required a ladder and removal of the screwed-on storm window and screen. If that happened twice in a decade it was a minor miracle.

My wife's elderly aunt used to wash our windows, but she died about 25 years ago.On window on the north side sometimes gets moderately interesting patterns at just the right temperatures, but never as elaborate as yours.
